GAF Driveway & Pavers Nationwide

GAF Driveway & Pavers: The West Palm Beach Owner’s Guide

We stock and install GAF-compatible driveway and paver components in West Palm Beach, with most replacement projects running $7,000-$18,000 for paver driveway installation and $5,000-$14,000 for full driveway replacement depending on substrate condition and square footage. We carry common GAF paver edge restraints, drainage channel grates, and permeable base materials on our trucks, and most part-specific repairs can be scheduled within a few business days. Homeowners usually discover the failure when they notice pooling after rain, shifting pavers along the perimeter, or a visible dip forming where the base has settled - often after a heavy Florida downpour exposes what dry months concealed.

Which GAF Models This Applies To

GAF’s hardscape line centers on permeable paver systems and the drainage infrastructure beneath them, not the pavers themselves - GAF sources the concrete units through partners like Belgard and Techo-Bloc while manufacturing the structural components that make the system work. The parts we replace most often are the GAF Aqua Flow edge restraints (available in 6-inch and 8-inch profiles), GAF StormDrain channel grates in 4-inch and 6-inch widths, and the GAF Soil Separation Fabric specified for their permeable installations.

To identify your part, check the stamped model number on the edge restraint channel - it runs along the interior face and starts with “GAF-AF” for Aqua Flow or “GAF-SD” for StormDrain series. The grate width must match the channel exactly; a 6-inch grate in a 4-inch channel will rock and crack, while a 4-inch grate in a 6-inch channel will sag and catch debris. For edge restraints, measure the exposed height from the bedding sand to the paver surface - 6-inch restraints suit standard residential driveways with 60mm pavers, while 8-inch handles commercial-grade 80mm units or deeper base courses common in West Palm Beach’s sandy soils.

We source OEM GAF components through authorized distributors in Palm Beach County. Aftermarket equivalents exist for edge restraints - Perma-Edge and Pave Edge make compatible profiles - but we specify OEM for any system still under GAF’s system warranty because mixing manufacturers can void coverage on the drainage performance guarantee. For grates, we stock OEM only; the load ratings and slot geometry are tested as a system, and a generic grate rated for pedestrian traffic will fail under a delivery truck in a West Palm Beach driveway.

Signs Your GAF Driveway & Pavers Is Failing

• Standing water 30 minutes after rain stops. The GAF StormDrain channel is either clogged with sediment or the grate has settled below the paver plane. In West Palm Beach’s afternoon thunderstorm pattern, a properly functioning permeable system should clear visible surface water within 15-20 minutes.
• Pavers rocking under foot or tire. The edge restraint has pulled away from the perimeter, allowing the bedding sand to migrate outward. Once the sand escapes, the paver loses its locked position and the interlock that distributes load across the whole field.
• Visible dip or hump developing along the driveway centerline. The aggregate base has settled unevenly, often where the GAF Soil Separation Fabric was punctured during installation or where organic material in the native soil has decomposed. Florida’s high water table accelerates this when drainage is compromised.
• Weeds or grass growing between pavers in a supposedly sealed joint. The joint sand has washed out, which means either the edge restraint failed and allowed erosion, or the bedding layer beneath has become fluid enough to pump sand up and out during rain events.
• Grate edges crumbling or channel walls bowing outward. The StormDrain channel is seeing loads beyond its rating, or the surrounding concrete collar has cracked and no longer transfers weight to the base. This is common where homeowners park heavy vehicles on grates not rated for point loads.

Replacement Cost & What’s Included

The spread in these numbers comes down to three things we assess before writing any price: the condition of the existing base (can we salvage it or must we excavate and recompact), the square footage, and whether the project requires a full GAF system replacement or just component-level repair. A localized edge restraint failure on a 400-square-foot driveway might run $1,200-$2,800 if the base and drainage are sound. A full replacement with new Aqua Flow edge restraints, StormDrain channels, base course, and pavers will land in the table range above.

Every quote we deliver is a flat written price with a written scope - under Clause 1 of the Haven Standard, the number is fixed before anyone touches a tool. The price includes parts, labor, compaction testing where required, and disposal. We pull permits when the project crosses that threshold, and every job carries our 365-Day Done Right Promise: if it’s not done right, we make it right.

DIY or Call Us?

There’s a honest line here. A homeowner can safely lift a few pavers, check whether the edge restraint is still anchored, and clear debris from a StormDrain grate with a shop vacuum - that’s reasonable owner-level maintenance. What goes wrong is the step after: assuming the fix is just “put it back and tamp it down.” Bedding sand gradation matters (ASTM C33, concrete sand, not masonry sand or play sand), edge restraints need spiral steel stakes at specific spacing, and base compaction requires a plate compactor running at the right moisture content - too dry and it won’t lock, too wet and it pumps.

We’ve been called to West Palm Beach homes where a weekend repair looked fine in January and had sunk three inches by July because the base wasn’t compacted in lifts. The cost to fix the fix usually exceeds the original repair quote. If you’re seeing structural failure - base settlement, channel collapse, or multiple edge zones failing - the substrate is telling you something that needs diagnosis, not just patching. Call (561) 475-3903 and we’ll schedule a free estimate with a written price before any work starts.
